this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...

The research aims to utilize polyethylene (PET), polypropylene (PP) and polystyrene (PS) plastic waste into liquid fuel by the pyrolysis process, currently, especially in Surabaya, a lot of waste, 13% - 14% is plastic. results sample from this study are distinguish temperature steam entering condenser also water condenser. And what will later be tested that oil close type gasoline or diesel. fo...

Natural gas plays a growing role in the energy mix by displacing coal due to its relative economic and/or environmental advantages A process of natural liquid (NGL) recovery utilizing internally generated achieve efficiency was designed. The utilizes heat from compressor end turbo-expander provide required maintain appropriate operating conditions at intermediate and bottom sections demethanize...

ABSTRACT: This paper focuses on design of nonlinear power plant controller using immune based multiobjective fuzzy approach. The thermal power plant is typically regulated by the fuel flow rate, the spray flow rate, and the gas recirculation flow rate. However, Strictly maintaining the steam temperature can be difficult due to heating value variation to the fuel source, time delay changes in th...

This paper is concerned with calculating boiler efficiency as one of the most important types of performance measurements in any steam power plant. That has a key role in determining the overall effectiveness of the whole system within the power station. For this calculation, a Visual-Basic program was developed, and a steam power plant known as El-Khmus power plant, Libya was selected as a cas...

This article presents the results of a techno-economic analysis repowering coal-fired power plant’s steam turbine system to instead accept heat produced by pressurized water reactor-type small modular nuclear (PWR SMR). type challenge due significantly lower pressure and temperature system. A 460 MW supercritical unit with parameters 28 MPa/560 °C/580 °C, operated in Łagisza Power Plant Poland,...

Solar parabolic concentrating collectors are widely and efficiently used in electrical generation. They were experimentally validated in worldwide pioneer plants. SEGS-VI 30 MW solar power plant built in southern California is one of these plants that was commissioned many years ago. In this work a possibility of installing such plant in Makkah, 21.4 °N located in moderate latitudes is studied....

The optimal synthesis and design of thermal power plants is best addressed using mathematical optimization techniques. However, conventional optimization methods require the user to manually define a priori the potential solution space through the modeling of a superstructure, which is a timeconsuming, complex, and error-prone task. More importantly, the final superstructure model can not guara...
